EU Cyber Resilience Act (CRA) — First Deadline September 2026

If you sell LabVIEW-based software and systems in the EU, please be aware that new CRA regulations may require you to implement security vulnerability reporting starting September 11, 2026. The VIPM Team has prepared guides to help you understand how this applies to your software applications and published packages, since it's important you understand these regulatory requirements (click the Learn More link to read these guides). Thank you for your help in keeping security front-and-center within the LabVIEW community.

Description

This library provides functions to compose and decompose objects, clusters, maps and sets in LabVIEW - effectively breaking encapsulation by making private data accessible.

Use with caution!

Known issues
- Decompose Set is not safe to use in LabVIEW 2019 to 2023 Q3 because of a known issue in the Variant To Flattened String primitive. It was tracked under issue number 2058864 and fixed in LabVIEW 2024 Q1.
